Str-replace 函数

Sass 提供了一系列方便的函数来操作字符串，但是没有函数可以将子字符串替换为另一个字符串。如果您需要，这里有一个快速str-replace函数。

/// Replace `$search` with `$replace` in `$string`
/// @author Kitty Giraudel
/// @param {String} $string - Initial string
/// @param {String} $search - Substring to replace
/// @param {String} $replace ('') - New value
/// @return {String} - Updated string
@function str-replace($string, $search, $replace: '') {
  $index: str-index($string, $search);
  
  @if $index {
    @return str-slice($string, 1, $index - 1) + $replace + str-replace(str-slice($string, $index + str-length($search)), $search, $replace);
  }
  
  @return $string;
}

用法

.selector {
  $string: 'The answer to life the universe and everything is 42.';
  content: str-replace($string, 'e', 'xoxo');
}

结果

.selector {
  content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
}
